I have created a web app using AI-assisted coding / vibe coding. The app is already running to some extent, but it is not properly built like a professional SaaS product. Since I am not a programmer, I need an experienced developer to review the entire codebase, clean it up, fix issues, and make it more stable and secure. This is not a project to build a new app from scratch. The basic version already exists, but because it was vibe-coded, I believe there may be messy code, poor backend structure, frontend-backend connection issues, bugs, security problems, and things that are not production-ready. I need someone who can actively work with me, understand what the app is supposed to do, inspect the current setup, and then properly fix and improve it. What I Need Help With The developer should be able to: 1. Review the full codebase 2. Understand the current frontend and backend setup 3. Check if the frontend and backend are connected properly 4. Fix bugs, broken flows, and backend issues 5. Clean up messy or unnecessary code 6. Improve the project structure 7. Check for security vulnerabilities 8. Secure API keys, backend logic, user data, and database access 9. Make sure users cannot bypass payments, credits, limits, or subscriptions 10. Improve reliability and stability 11. Make the app closer to a production-ready SaaS product 12. Explain the problems and fixes to me in simple language Ideal Freelancer I am looking for someone experienced in: * Full-stack development * Frontend and backend debugging * SaaS web apps * API integrations * Authentication systems * Payment/subscription systems * Database setup and debugging * Security review * Code cleanup and refactoring * Fixing AI-generated or vibe-coded projects Experience with messy MVPs or AI-coded projects is a big plus. First Step Before making major changes, I want the freelancer to first audit the app and tell me: * What is currently wrong * What is broken or risky * What needs to be fixed urgently * What can be improved later * Whether the current codebase can be cleaned up or needs partial rebuilding * Estimated time and cost for the fixes Deliverables At the end of the project, I expect: * A clear audit of the current app * Cleaned and improved code * Fixed frontend-backend connection issues * Fixed bugs and backend problems * Improved security * Better project structure * A more stable working version * Basic documentation explaining what was changed * Suggestions for future improvements Communication I am a non-technical founder, so I need someone who can explain things clearly and work with me step by step. I do not want generic promises. I need someone honest who can look at the project properly and tell me what is actually wrong.

Hi there, As I have experience with vibe coding, AI-assisted MVPs, and cleaning up production systems built through rapid development workflows, so I can help you properly stabilize, restructure, secure, and optimize your existing SaaS application. Once you share the current codebase, stack details, hosting setup, APIs, database structure, and current issues, I can first perform a full audit of the frontend, backend, authentication flow, payment/subscription handling, database structure, API connections, and overall security risks. I will then clean up the messy code structure, fix broken frontend-backend flows, secure sensitive logic and API keys, improve project architecture, optimize performance, fix vulnerabilities, and make the platform significantly more stable and production-ready while explaining everything in simple non-technical language. I would request to connect once so we can review the current application properly and discuss the most critical fixes first before moving toward long-term improvements. Thanks, Rahul A.

Hi there, We’ve worked on several AI-driven web apps, including one that used OpenAI’s GPT-3 to generate product descriptions. We also built a Chrome extension that allowed users to select text and generate descriptions based on that input. This experience gives us a strong foundation in developing AI-driven products. We understand that a product is only as good as its underlying code. That’s why we prioritize code quality and security as much as we do with features. We’ve worked with multiple startups as dedicated developers, so we know how to balance speed with delivering a stable, production-ready product. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil

I can do this. I’ll go through the codebase properly, figure out what’s actually wrong, what’s risky, what can be cleaned up, and what genuinely needs rebuilding instead of wasting time changing random things. You’ll get a clear audit in plain English first, then we can fix the important parts step-by-step and make the app feel like a real SaaS product instead of a fragile MVP. I’m also fine working with non-technical founders, so communication won’t be a problem.

Hi! The fact that your web app was "vibe-coded" using AI really matters here. These projects often look fine at first, but bugs, security gaps, and unreadable code pop up fast when you need to scale or charge real users. I've cleaned up multiple AI-assisted SaaS codebases before, including two platforms where the founders weren't technical and needed step-by-step review and plain-English advice. This is core work for me — not just new builds, but also fixing and securing messy MVPs. I'd start by running a full code audit, tracking problems in plain language. I'll map the frontend, backend, and connections, and list every bug or risk I find. Security checks and fixing payment bypasses are a top priority for real SaaS stability. One quick question — do you know which framework it was mainly built in (like Node.js, React, etc.)? Helps me prep for the first look. Happy to send you a simple no-jargon report listing every broken or risky part for free before any changes. You can also see examples of similar review work at work.techindika.com. — Pradeep

Hey, I can definitely help with this. I’ve worked on AI-generated MVPs and “vibe-coded” apps before, and usually the biggest issues are messy architecture, insecure backend logic, weak payment protection, unstable integrations, and frontend/backend flows that work only partially. My first step would be a proper audit of the existing codebase so you get a clear picture of what’s actually happening technically, what’s risky, what needs urgent fixes, and what can wait. I’ll explain everything in simple language without overcomplicating things, so you can make informed decisions even without a programming background. After the audit, I can clean up the structure, fix broken flows, secure sensitive parts, improve stability, and move the app closer to a real production-ready SaaS product instead of just an AI-generated prototype. Send me the current stack/repo details whenever you’re ready and I’ll take a proper look. Waiting for your response

I can step in as a full‑stack developer to clean up, fix, and properly secure your vibe‑coded web app, while keeping everything that’s already working for your users. I’m comfortable taking over AI‑generated codebases and turning them into something stable, maintainable, and production‑ready. I’ve worked on several projects where founders used AI to get an MVP out quickly, then needed a developer to harden the code, remove fragile patterns, and close security gaps without breaking existing flows. My approach would be to first map the current architecture, identify critical bugs and security risks, refactor the worst problem areas, add missing validations and access controls, and then introduce basic logging/monitoring so you can trust what’s in production. Quick question before I suggest an approach: Do you have a list of the most urgent issues and any error logs, or should I start with a full audit of the app?

Hello, This is exactly the kind of project I can help with. I have experience working on AI-generated/vibe-coded MVPs that function initially but are not structured securely or professionally for production SaaS use. Instead of rebuilding everything blindly, I first perform a full technical audit to understand: • Current frontend/backend architecture • API and database structure • Authentication and payment flows • Security risks and exposed logic • Performance bottlenecks • Broken or unstable workflows • Code quality and maintainability I can then explain in simple non-technical terms: • What is broken or risky • What needs urgent fixing • What can wait until later • Whether cleanup is possible or partial rebuilding is smarter I can help with: • Full-stack debugging • Frontend/backend connection fixes • API integrations • Payment & subscription protection • Authentication/security hardening • Database cleanup and optimization • Refactoring messy AI-generated code • Production-readiness improvements Important areas I usually check in vibe-coded apps: • Exposed API keys/secrets • Client-side payment bypasses • Weak authentication/session handling • Broken validation/security rules • Duplicate or unnecessary code • Poor database queries and unstable backend logic Relevant projects: • Time2Cash • Budgem • DaveSafeTrack I communicate clearly and work step by step with non-technical founders throughout the process.

Hello, This is exactly the kind of project I work on — taking AI-generated/vibe-coded MVPs and turning them into stable, secure, production-ready SaaS products. I understand the common issues with AI-built apps: messy architecture, weak backend validation, insecure API handling, broken frontend/backend flows, payment bypass risks, duplicated logic, and code that works “for now” but won’t scale reliably. My process starts with a full technical audit of your current app. Phase 1: Audit & Assessment • Review entire codebase and architecture • Inspect frontend/backend integration • Identify bugs, security risks, and unstable flows • Check auth, database access, subscriptions, limits, payment enforcement • Assess whether cleanup or partial rebuild is smarter • Deliver a clear non-technical report Phase 2: Cleanup & Stabilization • Refactor messy code • Fix backend/frontend connection issues • Secure API keys, auth flows, DB access • Lock payment/credit/subscription enforcement • Improve structure, reliability, and maintainability • Add documentation so future development is easier I’ll explain everything plainly and honestly — no vague promises, just practical fixes and clear recommendations. Once I review the codebase, I’ll tell you exactly whether it can be cleaned properly or needs selective rebuilding. Best regards, Doan
